2011 Annual Report
1. Leibniz Center for Informatics at Schloss Dagstuhl
Stimulating Exchanges in Relaxed Surroundings
The mission of the Leibniz Center for Informatics (LCI) at Schloss
Dagstuhl is to promote world-class research in informatics, support
leading-edge continuing education and professional development, and
promote the exchange of knowledge and findings between the academic
community and industry.
Founded in 1990, the Center hosts research seminars at which promising
young research scientists are afforded the opportunity of discussing their
views and research findings with the international elite of their field in a
specific cutting-edge field of informatics. The seminars enable new ideas
to be showcased, topical problems to be discussed, and the course to be set
for future development in the field.
A proposal is submitted for a seminar or perspectives workshop by a small
group of scientists of international standing in the respective field. The
Scientific Directorate is responsible for approving the proposals and the
participant lists. Participation in these events — for the most part one week
in length — is possible by way of personal invitation only by the Center.
The Center assumes part of the associated costs in order to enable young,
promising scientists and doctoral students to participate.
In keeping with the Center’s overall idea and philosophy, lounges and
working areas are also featured which invite the visitors to get together in
small groups outside of the official conference offerings for connecting
one on one or doing work in the research library. The Center has three
lecture halls, a number of conference rooms, a comprehensive research
library, and 64 rooms with 75 beds. A guest house constructed in 2011 and
providing for 71 rooms with 89 beds has enabled the Center’s capacity to
be increased since January 2012.
In 2011 one or more Dagstuhl Seminars or Dagstuhl Perspectives
Workshops were booked at the Center during 45 weeks of the year.
Gatherings of smaller workgroups were hosted in parallel to the seminars.
The facilities were available for summer schools and other informatics
conferences and events during the weeks when they were not being used
for Dagstuhl Seminars. In addition, individuals were accommodated for
research stays. There is only one condition applicable to all the offerings:
They have to be related to informatics.
Schloss Dagstuhl is located in the charming countryside of northern
Saarland, in the tri-country region formed by Germany, France and
Luxembourg. As they say, location is everything, which is why Schloss
Dagstuhl offers a host of possibilities for “getting up close and personal”
Page 7
Schloss Dagstuhl
with nature. Yet Schloss Dagstuhl is also conveniently located, as it is near
the Saarbrücken-Trier-Koblenz and Kaiserslautern-Trier autobahns,
meaning it can be easily reached from Saarbrücken, Trier and
Kaiserslautern in less than an hour.
Structure of the Center
The Center is operated as a non-profit organization whose associates
include the Gesellschaft for Informatik e.V. (GI, or German Informatics
Society), of Bonn, Saarland University, the Technical University of
Darmstadt, and the Universities of Frankfurt, Kaiserslautern, Karlsruhe,
Stuttgart and Trier. Other associates of the Center include: three research
institutes of international renown, i.e. French National Institute for
Research in Informatics and Automatic Control (INRIA), of Rocquencourt,
France; Dutch National Research Institute for Mathematics and
Informatics (CWI), of Amsterdam, Netherlands; and the Max Planck
Society (MPG), represented by the Max Planck Institute for Informatics, of
Saarbrücken, Germany.
By resolution of the Federal Government–State Commission for
Educational Planning and Research Promotion (BLK) in 2005, the Center
was included as a research service institution in the joint funding of the
German federal and state governments (Blue List). The Center is a member
of the Leibniz Association. This was documented towards the outside
world in 2008 when the Center officially changed its name from
“International Conference and Research Center for Computer Science
(IBFI)” to “Leibniz Center for Informatics (LCI)”.
The LCI was evaluated for the first time in July of 2009. The findings of
the Evaluation Commission of March 2010 showed a positive image and
established that the LCI achieves outstanding success in its commitment to
its designated task of supporting the international informatics research
community by providing a seminar center for academic events. 1
Dagstuhl Bodies
The following five bodies are in charge of the activities offered at the
Center (for the body members, cf. Annex 1):
Associates’ Meeting
The representatives of the Associates’ Meeting convene meetings of the
Supervisory Board and are responsible for amendments to the articles of
incorporation and the admission of other associates.
For more information, refer to article of 20 April 2010 in the News section at
Page 8
2011 Annual Report
Supervisory Board
The Supervisory Board is responsible for ensuring that management
complies with the Center’s objectives in a meaningful legal and economic
manner. It is involved in all essential matters pertaining to research and
financial planning.
It is composed of four representatives of the German Informatics Society
(GI), one representative each of the three founding universities (Saarland,
Karlsruhe, Kaiserslautern), two representatives of the universities that
subsequently joined (Darmstadt, Frankfurt, Stuttgart, Trier), and one
representative each of the federal government and the two host state
governments (Saarland and Rhineland-Palatinate). The members of the
Supervisory Board hold office for four full fiscal years. The Supervisory
Board convenes meetings of the Scientific Directorate and of members of
the Scientific Advisory Board and the Industrial Curatory Board.
Scientific Directorate
The Scientific Directorate is responsible for the Center’s seminar program.
It reviews the proposals for the Dagstuhl Seminars and the Dagstuhl
Perspectives Workshops and decides whether they merit approval. It
reserves the right to approve the focus of topics and the individuals
included in the participant group. It also makes recommendations to the
Scientific Directorate concerning seminar topics when individual
informatics fields are not well represented, and develops new event
The Scientific Directorate is comprised of one informatics professor from
each of the university and research center associate members, and four GI
delegates. Of these individuals, two are nominated by the GI’s Executive
Board and two by the GI’s Advisory Board of University Professors
(GIBU), which is independent of the Executive Board. The Scientific
Directorate is comprised of a total of 14 members. The members and the
Scientific Director hold office for three years.
The members elect a Scientific Director from their midst. Professor
Reinhard Wilhelm (Saarland University) has been the Center’s Scientific
Director since its founding.
Scientific Advisory Board
The members of the Scientific Advisory Board are internationally diverse.
The Board’s purpose is to lend critical support in the management of the
Center with regard to its scientific orientation and the user orientation of its
service offerings, and in policy decisions pertaining to the Center’s
continued development. Its task is to advise the Supervisory Board and
Scientific Directorate in a scientific or subject-matter capacity. Another
task is to evaluate the Center’s performance and achievements and draft a
status report including position paper and recommendations (audit) for the
Page 9
Schloss Dagstuhl
Senate Evaluation Committee of the Leibniz Association. The Board
convenes once a year together with the Industrial Curatory Board.
Industrial Curatory Board
The Industrial Curatory Board performs a transmission function between
the Center and the R&D departments and labs of industry. It also has the
task of securing the acceptance of the Center by government authorities
and industry and, being a promotional organization, expanding the
Center’s economic base. The members of the Curatory Board support the
Center in identifying current R&D topics for seminars and locating
attractive organizers in industry.
The Curatory Board is regularly called upon to propose suitable
participants for seminars known to it from its activities.
The Dagstuhl Team
The executive management of the Center is in the hands of its Scientific
Director, Prof. Reinhard Wilhelm, and its two Technical Administrative
Directors Wolfgang Lorenz and Dr. Christian Lindig. The Center’s staff
totals 42, many of whom work on a part-time basis. 21 staff members are
charged with academic and administrative tasks or overseeing the library
and IT systems, and 21 with housekeeping, running the kitchen and
resolving maintenance issues involving our guests. The Center employs
two second-year trainees. With the exception of three academics who
receive third-party funding, all positions are funded under the core budget.
The academic staff supports the seminar organizers, serves the Center’s
bodies, and tends to the publications of guests. The Center has close ties to
the GI’s Advisory Board of University Professors (GIBU) through Dr.
Marc Herbstritt, a GIBU associate member.
Prof. Reinhard Wilhelm Recipient of the ACM Distinguished
Service Award
The Association for Computer Machinery (ACM), the world’s largest
educational and computing society, named Prof. Reinhard Wilhelm
recipient of the Distinguished Service Award in April of 2011 in
recognition of his many years of service on the Center’s behalf. This
distinction is awarded on the basis of value and degree of services to the
international computing community.
In so doing, the ACM recognizes Prof. Wilhelm’s contributions and
endeavors since 1990 in transforming the Center into an informatics venue
of international prestige that attracts and inspires scientists throughout the
world. The program and infrastructure that he and the Dagstuhl team have
established and continuously developed during his term have benefited
renowned scientists who have transformed the computing world.

2011 Annual Report
PR Work and Media Relations
Press releases are a key platform for showcasing current informatics topics
in a readily understandable manner and disseminating them. They also
serve to make the Center and its concept more well known to a large
audience. Press releases and reports appearing in various media that come
to the Center’s attention are available on the LCI’s portal at:
The Center continues to maintain close ties to Computerclub Zwei (cf.
http://www.cczwei.de). Dagstuhl will provide interview partners on
request and copy for publication on the cczwei website. Thanks to the
support of the Saarland Broadcasting Association, Dagstuhl has access to
professional reporting equipment that enables broadcast journalists to
conduct interviews with seminar participants in digital lossless audio
Dagstuhl has become a port of call for journalists seeking to report on
specific computing topics, and on Dagstuhl itself.
In order to encourage young journalists and trainees to report on complex
computing topics, Dagstuhl offers a workshop on science journalism every
year. In 2011 the workshop took place from 25 to 28 September in parallel
with the Dagstuhl Seminar “Public-Key Cryptography”, of which several
participants were involved in the journalists’ practical work.
The Center disseminates news on the Dagstuhl program via social
networks such as Twitter (@Dagstuhl) and LinkedIn. Twitter is used
primarily to disseminate program announcements. A Friends of Schloss
Dagstuhl group is maintained at LinkedIn, whose objective is to support
the networking of the participants of the Dagstuhl Seminars. Interesting
news items pertaining to Dagstuhl are also disseminated. Membership in
the group is by invitation only through Dagstuhl. There are now so many
membership requests that approval is subject to proof of participation in a
Dagstuhl Seminar. The group currently numbers 367 members.
Open House on 18 June 2011
The LCI’s Open House was held on 18 June 2011 as part of Wadern’s
historical celebration and town fair (“Waderner Maad”). Everyone was
afforded the opportunity to become acquainted with scientists and the
fields they work in and to learn something about how innovative
computing applications function. There were also presentations on the
Dagstuhl concept and historical tours of the manor house and to the
Dagstuhl castle ruins.

Exhibition “Octavie de Lasalle von Louisenthal and Schloss
To commemorate the bicentenary birth of Octavie de Lasalle von
Louisenthal, a multifaceted, vibrant exhibition was organized in
association with the City of Wadern in the cloister of the new building to
celebrate the life and works of this painter baroness. Octavie was equally
informed of German and French culture. When considered in the context
of the de Lasalle von Louisenthal family, the special appeal of this
exhibition lies in its affinity to a venue that is synonymous with an
international forum.
Apart from the art works on loan from various collections, the exhibition
also included works of Octavie that are at home in Dagstuhl, in addition to
the chapel painted by her and the stations of the cross. The flair of the
environs of the former residence of the de Lasalle family and the “painter’s
cottage” on the castle hill could also be explored during a walk.
Curator of the exhibit: Dr. Thomas Wiercinski, art historian
Sponsors and Donors of the Center
In addition to the funding from the German federal government and state
governments, the Center also receives donations and contributions from
other sources.
Page 13
Schloss Dagstuhl
During 2011 the Informatics Research Library received book donations
from the following publishers:
• Eurographics Association
• Oldenbourg
• O’Reilly
• SIAM Society for Industrial and Applied Mathematics
• Springer-Verlag
The library also receives numerous book donations from seminar
participants. The Center is grateful for donations of author’s copies,
particularly those of major works which are out of print. The Center
received a total of 1,002 volumes during the year under review as
donations from publishing houses and seminar participants.
Schloss Dagstuhl Informatics Center Foundation
The Leibniz Center for Informatics (LCI) is recognized by the German tax
authorities as a non-profit organization. Through the end of 2005, the
Center was financed jointly by the Saarland and Rhineland-Palatinate state
governments, this financing being supplemented by donations from
various sponsors in industry and by publishing houses. The Center has
received federal and state funding since 2006.
The financing regulations imposed on the Center by public funding did not
allow for much leeway in the Center’s fiscal planning and expenditure; this
led to the establishment of the Schloss Dagstuhl Informatics Center
Foundation, making it possible to react flexibly to unforeseen challenges.
The sole purpose of the Foundation is to promote the Center's objectives as
stated in its articles of incorporation, in particular by providing funding for
the promotion of young scientists and for the Center's Informatics
Research Library from income generated by the Foundation’s assets and
from donations and contributions of third parties earmarked for this
purpose. Young researchers are fostered by grants for participation in
seminars organized by the Center, for research stays at Schloss Dagstuhl,
or for temporary projects.
Dagstuhl can be supported via the Foundation in various manners:
Contributing member, individual membership
The Foundation’s contributing members are the exclusive recipients of an
annual scientific publication detailing the results and findings of the
Dagstuhl Seminars, in addition to this Annual Report including the
program of the Dagstuhl Seminars and other events hosted at the Center.
Page 14
2011 Annual Report
Members can determine the amount of their annual membership fee
themselves, however they should commit to a minimum of €60.
Contributing member, corporate/institutional membership
Minimum annual membership fee: €600 for educational institutions,
€1,200 for corporate and other members.
Sponsoring of individual events
The Center provides a forum enabling companies to partake in its high
renown and events. A donation can be allocated to a specific Dagstuhl
Seminar or Dagstuhl Perspectives Workshop. Sizable contributions are
given honorable mention via the Internet and other media (example:
The Foundation received donations from companies
organizations for the following seminars in 2011:
Microsoft Research, Cambridge, UK:

USA), Anita De Waard (Elsevier Labs – Jericho VT, USA), Ivan Herman
(CWI – Amsterdam, Netherlands), Eduard H. Hovy (University of
Southern California – Marina del Rey CA, USA)
Corporate Donations
The Foundation continues to be dependent on the generous contributions
and donations of companies, as the Foundation’s assets have not yet
reached the level as provided for in its articles of incorporation (€500,000).
The Foundation is recognized by the German tax authorities as a non-profit
organization, meaning that contributions and donations to German
organizations are tax-deductible.

2. Events at Dagstuhl
The Center fulfills its designated tasks by organizing and hosting scientific
seminars, and by providing the facilities offered by the Center for
conducting various informatics conferences and working retreats.
Dagstuhl Seminars
The Dagstuhl Seminars are accorded top priority in the Center’s annual
program as they are a key instrument for promoting research. The Dagstuhl
Seminar program for the year under review (2011) is to be found in Annex
2. An up-to-the-minute program covering the coming 18 months is
available on the Dagstuhl website. The spectrum of the seminar topics
provides an excellent if not comprehensive view of the areas currently
under discussion in the international informatics arena. The topics of the
seminars planned for 2011 and 2012 point to the following future trends:
• Data Structures, Algorithms, Complexity
• Cryptography, Security, Data Protection
• Semantics, Logic, Verification
• Modeling and Simulation
• Software Engineering
Dagstuhl’s distinguishing accomplishment is the establishment of
pioneering, interdisciplinary seminars that have virtually become
institutions unto themselves. Many topics dealt with in depth at Dagstuhl
subsequently develop into highly active research fields, resulting in some
cases in DFG priority programs and other grant and funding programs.
Various Dagstuhl Seminars have succeeded in bringing groups of
researchers and scholars of various areas and disciplines together for the
first time. To be sure, these individuals were involved in research on
associated issues, methods and techniques, however they hadn’t been able
to benefit from a common discussion platform. This applies in particular to
disciplines outside of the field of informatics. Key R&D areas for which
in-depth collaboration with informatics specialists was initiated and
consolidated at Dagstuhl: biology (since 1992) and sports (since 2006).
Topical interdisciplinary topics include: social networks, e-democracy,
logistics and music. These initiatives received special mention in the
evaluation conducted of the LCI.
Dagstuhl Perspectives Workshops
The Dagstuhl Seminars are supplemented by Dagstuhl Perspectives
Workshops, which focus on subfields or are interdisciplinary in nature,
thus covering more than one informatics field. These workshops are
designed to generate recommendations for research donors and sponsors
Page 16
2011 Annual Report
and give impetus to research projects and Dagstuhl Seminars for key
informatics areas.
The workshops are designed to
• contribute to an analysis of the present status of a field
• tap into potentials and development perspectives of existing fields of
• detect shortcomings and problematic developments, particularly in
the German research landscape
• show research directions
• trigger innovation processes
For the most part, the workshop participants are 25–30 scientists of
international standing in their respective fields who cover all subfields and
sub-aspects. Instead of reporting from current research results, the focus is
on presenting position papers which outline the current status in the field,
open issues, shortcomings and problematic developments, and promising
directions. The results of the in-depth discussions are presented in a
manifesto detailing the open issues and possible research perspectives for
the coming 5-10 years. The Center coordinates the targeted dissemination
of this manifesto as research policy impulses to German and other
European research donors and sponsors (EU, German Federal Ministry of
Education and Research, DFG, etc.).
Abstracts of the manifestos are regularly presented in a forum of
Informatik-Spektrum (published by Springer).
The following Dagstuhl Perspectives Workshop were conducted in 2011:
Online Privacy: Towards Informational Self-Determination on the
• The Future of Research Communication
For more information on the Dagstuhl Perspectives Workshops and their
results, see: http://www.dagstuhl.de/pw-list
Other Events
Other events are hosted at the Center apart from the Dagstuhl Seminars
and Dagstuhl Perspectives Workshop, i.e.
• GI-Dagstuhl seminars, bringing together young scholars for a
specific topic. They are conducted by the German Informatics
Society (GI) in association with the LCI.
Page 17
Schloss Dagstuhl
• Summer schools, continuing education offerings of the German
Informatics Society (GI) and German Informatics Academy (DIA),
CPD for teachers and instructors, education and training of young
journalists and trainees.
• Departmental conferences of graduate colleges, GI specialist groups
and other academic and industrial working groups
• A small number of international informatics conferences
Research Stays
Many people regularly take advantage of Dagstuhl’s offer of using the
Center for research stays. In most cases these are individuals who wish to
use the Center as a retreat for several weeks in order to devote themselves
to their studies undisturbed. In 2011, four research guests availed
themselves of this opportunity.
Utilization of the Center
94 events with ca. 2,900 guests were featured in 2011, making for ca.
10,833 overnight stays and a slightly lower utilization rate as compared to
previous years. This pertains to working retreats and CPD events in
particular; their average length was shorter and there were fewer
participants. With 80 proposals received in 2011, the Dagstuhl Seminars
and Perspectives Workshops continue to be most popular events. Dates for
three-day events are increasingly being offered and the number of
participants reduced to 30 in some cases, enabling two events to be
organized in parallel.
Working retreats generally use this event format. The result is that three or
more events take place in parallel and in sequence during many weeks.
The weekends were kept free in 2011, as well as two weeks in August and
at the end of the year, this time being required for maintenance work to
building facilities and administrative work. Apart from a few isolated
periods and a series of as yet unbooked parallel event slots for groups of up
to 20 participants, the Center is booked up through December of 2013
(status: February 2012).
The following charts show the increase in usage figures according to
events and participants since the Center was founded, along with a
breakdown according to the different event types. For more particulars on
the various events in 2011 (date, title, organizer, etc.), please refer to
Annex 2. Dagstuhl’s website contains the program of upcoming events and
further information and material on all events past, present and future, e.g.
objective, participant list, concluding report and, in some cases, references
to in-depth information.

Schloss Dagstuhl
Quality Assurance
The Center conducts surveys of the participants of the Dagstuhl Seminar
and Dagstuhl Perspectives Workshop, the questionnaire containing
questions about their satisfaction with the content of the event and the
organization of their visit. The results of each questionnaire are made
available to all of the Center’s departments every week via e-mail, this
enabling a quick response to issues and requests. At the same time the
anonymized results of the content questions are made available to the
seminar participants via e-mail, typically in the week following their stay
at the Center. This enables the organizers to receive feedback on how the
seminar went and tips for organizing future seminars.
The chart below shows the satisfaction of these participants in 2011 with
regard to selected aspects of their stay. The results were compiled from
1,005 questionnaires, representing the responses of 51% of all participants.
These excellent results are not only a recognition of the Center’s past work
but also pose a challenge to its future work.
Page 20
Event Participants
2011 Annual Report
At 73% the proportion of foreign guests in Dagstuhl Seminars was
extremely high again during 2011 (European countries except for
Germany: 41%). The following chart shows the distribution according to
area of origin of our Dagstuhl Seminar and Dagstuhl Perspectives
Workshop guests in 2011. For a detailed breakdown of the countries of
origin of all the participants of Dagstuhl events, please refer to Annex 3.
To put it mildly, Dagstuhl Seminar and Dagstuhl Perspectives Workshops
participants are enthusiastic about the Center, i.e. they are quite taken with
the idea and concept of promoting informatics research in this manner, in
addition to being “enchanted” by the quaint manor house, the ambience
created by the Center, the research and discussion opportunities, not to
mention the Center’s surroundings, and the commitment and dedication of
its personnel.
Annex 4 contains a number of excerpts from written reports and thank-you
letters received by the Center.

3. Dagstuhl Publishing
In contrast to traditional conferences, the seminars at Schloss Dagstuhl are
primarily designed as an opportunity to develop new ideas instead of
presenting findings or final results. This means that a seminar is not
expected to lead immediately to scientific publications. High-caliber
publications that germinate in Dagstuhl don’t generally come to fruition
until two to three years later. Nonetheless the Center endeavors to
document the immediate scientific results of its events. This led to the
establishment of the Dagstuhl Reports periodical series in 2011, whose
monthly issues document the Dagstuhl Seminars and Dagstuhl
Perspectives Workshops of a month. This new series supersedes the
Dagstuhl Seminar Proceedings. The difference between the two is a final
report by the organizers and a collection of brief summaries of the lectures
are primarily featured instead.
Publishing comprehensive research articles related to a Dagstuhl Seminar
or a Dagstuhl Perspectives Workshop is now enabled by the Dagstuhl
Follow-Ups book series and the Dagstuhl Preprint Archive (in association
with arXiv/CoRR). The journal Dagstuhl Manifestos was also created for
Dagstuhl Perspectives Workshops in order to provide a central publication
platform for manifestos, whose drafting is an established component of
each Dagstuhl Perspectives Workshop.
Publications — Facts & Figures
In the Dagstuhl Reports series, 10 issues with a total of 44 articles were
published for 2011. Each issue is supplemented with a front matter page
containing a table of contents and outputted as a PDF file containing all the
articles of the issue.
Two manifestos were published in Dagstuhl Manifestos in 2011 (of events
10482 and 11061). The editorial deadline for the 2011 issue was the end of
February 2012 in order to include the publication of the manifesto of
11331 there.
Two books have been published so far in the Dagstuhl Follow-Ups series,
the first one in 2010, and the second one in 2011. In order to publish in this
series a separate proposal has to be submitted by the seminar organizers
that is reviewed by the Scientific Directorate. Three proposals were
submitted in 2011 (10452, 11041 and 12111), all three of which were
approved. Publication of these volumes will take place in 2012 and 2013.
Book projects generally require an extended lead time: 1–2 years from the
submission of the proposal until publication is not uncommon.
Due to its international reputation and independent status, the Center
received queries pertaining to the electronic publication of conference
Page 22
2011 Annual Report
volumes already in 2006. They document the scientific results of
conferences that did not take place at Dagstuhl and are traditionally
published by (commercial) publishing houses. In order to cater to this
demand, the Center created the LIPIcs and OASIcs publication series, in
which the following volumes were published in 2011:
of contributions
IARCS Annual Conference on Foundations of
Software Technology and Theoretical Computer
Science (FSTTCS’11)
Computer Science Logic (CSL’11) – 25th
International Workshop/20th Annual Conference of
Technical Communications of the 27th International
Conference on Logic Programming (ICLP’11)
22nd International Conference on Rewriting
Techniques and Applications (RTA’11)
28th International Symposium on Theoretical
Aspects of Computer Science (STACS’11)
11th Workshop on Algorithmic Approaches for
Transportation Modelling, Optimization, and
Systems (ATMOS’11)
Visualization of Large and Unstructured Data Sets –
Applications in Geospatial Planning, Modeling and
Engineering (IRTG 1131 Workshop)
Bringing Theory to Practice: Predictability and
Performance in Embedded Systems (PPES’11)
17th GI/ITG Conference on Communication in
Distributed Systems (KiVS’11)
Sixth Doctoral Workshop on Mathematical and
Engineering Methods in Computer Science
(MEMICS’10) – Selected Papers
Publication in the LIPIcs and OASIcs series is subject to a fee: A lump sum
of €250 is currently charged for publishing a volume in OASIcs; for LIPIcs
costs range between €500 and €750 depending on the number of articles in
a volume. The costs are generally assumed by the conference organizers.
The Dagstuhl Publishing items feature a number of characteristics that
differentiate them from other web publications and contribute to the
professional image provided by the Dagstuhl Publishing imprint:
Page 23
Schloss Dagstuhl
• Distinctive layout possessing substantial recognition value.
• Brand creation by virtue of logos (figurative and word marks).
• High-quality text layout and maintenance of metadata.
• Registration of digital object identifiers (DOIs) (in association with the
German National Library of Science and Technology, University
Library of Hannover).
• Economical, equitably-priced service offerings for publishing
conference volumes while providing for a qualitative selection.
During the year under review, Dagstuhl Publishing generated revenues of
€4,100 (net) through its publication services.
Back-end: DROPS
All items published by the Center are administered via the Dagstuhl
Research Online Publication Server (DROPS). The general guidelines
applicable to online publications (Dublin Core initiative)1 are adhered to,
meaning that all the requisite metadata on each publication is stored, thus
ensuring availability in the long term. This enables the online publications
to be cited and be accessible by a wide readership. The technical basis for
this is an adapted version of the OPUS system.2
For more information on DROPS, please refer to: dagstuhl.de/drops/.
Long-term Archival
All publications are submitted to the German National Library (D-NB) for
(digital) long-term archival.
All series are listed in the DBLP Computer Science Bibliography. See also:
• http://dblp.uni-trier.de/db/journals/dagstuhl-reports/index.html
• http://dblp.uni-trier.de/db/journals/dagstuhl-manifestos/index.html

• http://dblp.uni-trier.de/db/series/oasics/index.html
• http://dblp.uni-trier.de/db/series/lipics/index.html
The LIPIcs volumes are submitted to the Conference Proceedings Citation
Index (CPCI), maintained by the Thomson Reuters media group. In the
future the CPCI is to offer similar bibliometric evaluations such as the
“impact factor” of the Journal Citation Index. Yet the CPCI submission
Page 24
2011 Annual Report
procedure is very non-transparent and provides no feedback on inclusion in
the index.
The LIPIcs and OASIcs series are listed in the Directory of Open Access
Journals (DOAJ):
• http://www.doaj.org/doaj?func=openurl&genre=journal&issn=2190
• http://www.doaj.org/doaj?func=openurl&genre=journal&issn=1868
In order to prevent data loss, two cooperative ventures were initiated in
2010 for mirroring the content of the DROPS publication server:
• io-port.net: The informatics publication portal organized under the
auspices of io-port.net, FIZ Karlsruhe – Leibniz Institute for
Information Infrastructure, mirrors all volumes of the LIPIcs series
and links on the home page directly to the volumes mirrored.
For more information, see: http://www.io-port.net (Digital
Library/LIPIcs). In 2011 the existing affiliation was consolidated by
a memorandum of understanding. There are plans to integrate
Dagstuhl publications more strongly in the products of FIZ
Karlsruhe (e.g. Zentralblatt MATH, the world’s most comprehensive
reference database in mathematical research), however without
restricting unfettered access to publications).
• SunSite Central Europe: The Sun server park located at the
Aachen University of Technology and operated under the guidance
of Prof. Matthias Jarke offers a home for numerous software
archives and publications. All the DROPS assets are now mirrored at
regular intervals on the Aachen SunSite.
Open Access
Access to the documents published via DROPS is free of charge for
readers in keeping with the open access idea, which fosters unimpeded
access to scientific publications. By signing the Berlin Declaration on
Open Access to Knowledge in the Sciences and Humanities, the Leibniz
Association, and the Center as a member of the Association, are following
the example set by a large number of key international institutions for
R&D and research promotion. The vision jointly pursued by them is to
disseminate knowledge so that it can be easily accessed throughout the
world without any financial obstacles being imposed. The Internet enables
scientific work to be published without charging a fee for reading these

4. LCI+DBLP Project: Consolidation of the Bibliometric Basis in
Conference Facilities
Although substantial funding flows into R&D, decision-makers sometimes
find it difficult to identify promising research projects. This comes as no
surprise in view of the immense complexity and specialization of scientific
fields. The documentation of research work is instrumental in this context
for identifying successful research. However, the publication culture in
computer science cannot be gauged using traditional methods. In a
collaborative venture the Center and the University of Trier have come to
the aid of the computing community by way of the DBLP Computer
Science Bibliography, representing a consolidation of the open source
literature database. This project is financed by the Joint Initiative for
Research and Innovation of the Leibniz Association, which evaluates and
accepts or rejects project applications via the Senate Competition
Committee. The LCI+DBLP project is receiving funding for two years
(June 2011 to May 2013); it comprises two full-time positions in addition
to materials/supplies. Funding is supplemented by a donation of the Klaus
Tschira Foundation (€120,000 for two years), through which another fulltime position can be financed (from 2012), this position to focus in
particular on the evaluation of conferences and journals.
Enhancing Cataloguing and Processing Efficiency
The DBLP database records computer science literature at the level of
individual contributions. In selecting data sources, the DBLP concentrates
on publishing houses and digital libraries. This data has been captured over
a period of many years, with manual work comprising a sizable share of
the effort involved. Although this has resulted in an acknowledged
recognized high quality of data assets, it represents a substantial amount of
This circumstance led to the development by Oliver Hoffmann of software
in completion of his graduate degree thesis that collects the raw
bibliographic data of the websites of scientific publishers and digital
libraries. The method employed is similar to that used by a search engine
like Google that employs crawlers to automatically comb through
webpages and prepare the content for indexing. This software has
undergone continuous further development and enhancement in the project
and is now an integral component of the workflow involving the
cataloguing of data. To be sure, final quality assurance and error resolution
are still done by hand for the most part.
Page 26
2011 Annual Report
Thanks to the semi-automation of data capturing, cataloguing efficiency
has been boosted substantially. From May 2011 to the end of
December 2011 data assets were increased by 199,827 to a total 1,842,526
entries. On the whole, data assets grew by 308,643 data records in 2011.
Directory of All Conferences and Journals
All conferences and journals catalogued in the DBLP database can be
located by way of a keyword index. To date this has been maintained
manually: newly catalogued series have had to be entered under the
relevant keywords. This was not only laborious but error-prone as well: if
an entry was overlooked, it could not be located via the index. In the
course of systematizing data capturing the possibility was created of
having this index generated automatically. Keywords under which a
journal is to be catalogued can be conveniently selected in a central file.
Sorting of entries and creating the webpages is done by the software.
Another index by publisher was created enabling the journals of major
publishers or professional associations and societies that have been
catalogued to be viewed. This increases transparency and has been shown
to be quite useful in negotiation with the respective organizations.
Inclusion of the Center’s Research Library in the DBLP
One goal of the project is improving the cataloguing of monographs and
collected volumes. One of the first steps was the integration of the
collection of books contained in the Center’s research library. To this end,
assets amounting to 7,583 books were exported from the library’s
catalogue and integrated in the DBLP database. By performing quality
assurance manually, errors in the library’s data assets were detected and
remedied. Although the administration of these data assets had been
meticulous, numerous corrections and addenda had to be performed. Apart
from expanding the DBLP database, this also enabled the catalogue assets
of the Center’s research library to be enhanced.
Institutions as Entities in the DBLP
Efforts have been commenced to catalogue research institutions as entities
in the DBLP database. The goal of this is to enable the creation of
individual views for institutions and cross-linking between authors and
institutions. This is designed to enable bibliographic and bibliometric
analyses to be conducted at the institutional level. The data collected to
date extends to all member and guest institutions of the German Council of
Informatics Departments (FTI), and a series of the most significant
international institutions (currently 8,965 individuals in 169 institutions).
Page 27
Schloss Dagstuhl
Integration of External Rankings
Due to its limited resources the DBLP database can accommodate only
part of all journal, conference and workshop series. When capturing a new
publication series the question of the series’ priority is always posed. This
is why the CAPES (http://www.capes.gov.br/) and CORE
(http://core.edu.au/) ranking lists for conferences and journals have been
integrated in the back-end data assets. These rankings are designed to serve
as an aid until a dedicated bibliometric infrastructure can be established.
Workflow Management & Help Desk System
A professional workflow management application is to be established in
2012 in order to cater to the growth in the Dagstuhl team and to streamline
work processes. To this end, the Center succeeded in procuring a JIRA
license free of charge in December of 2011. The system is currently being
set up.
DBLP regularly receives e-mails from publishers, editors or authors
requesting that data be entered or modified. Some publishers already
provide metadata of new publications in a structured input format. It used
to be that there was a considerable delay in responding to e-mails like
these or they weren’t responded to at all. Although errors are corrected
promptly, notifying the sender to this effect was often dispensed with due
to time constraints. Consequently, the possibilities offered by the workflow
management system are to be utilized to administer queries of this type in
a coordinated manner. The senders are to receive feedback that their data
has been entered or the reasons explained why this wasn’t possible.
Senders reporting an error are to receive a short message indicating that
their correction has been entered. As a consequence this will enhance
transparency with regard to recording data while underscoring the integrity
of the DBLP. Senders will also receive positive signals that are designed to
motivate them to actively aid in expanding and improving data assets in
the future.
Error Report Portal
A web-based portal system has been set up in collaboration with the
Databases and Information Systems chair of the University of Trier for
submitting error reports. This system is designed to enable DBLP users to
report errors and inconsistencies in data assets in an easy and convenient
manner. The error reports generated in this manner are intended to provide
sufficient information so as to enable changes to be made to data assets in
a semi-automated manner. Plans have also been made to integrate this with
the workflow management system. The system is currently undergoing an
internal evaluation.
Page 28
2011 Annual Report
Standardized XML Format for the Submission of Data
In the past new data was submitted to the DBLP in many forms and
varying quality. This frequently resulted in more work having to be
invested in the entry of new data. A new XML format has been specified
for data submissions in order to simplify and standardize this process. The
new format is currently undergoing testing with individual selected data
providers. In the long term the submission of data is to also be supported
by a portal system so that problems in the data submitted can be detected
early on and remedied.
Networking of Data Providers
Maintaining contact with publishers, societies and professional
associations is necessary in order to keep abreast of new publications and
gain access to bibliographic metadata as early as possible. In many cases
publishers have proven to be continuous suppliers of data, an ideal
situation. Consequently an effort is being made to establish or expand
contacts with publishers in a targeted manner. The following publishers are
particularly noteworthy in this connection:
• Springer Science+Business Media
Springer has been supplying the DBLP database with metadata to all
new publications since May of 2011. The data is transferred to the
DBLP on a daily basis.
The Center has succeeded in getting IEEE to provide data to the DBLP
on a regular basis since October of 2011. The DBLP receives all the
newly catalogued items of the IEEE Xplore digital library on a weekly
Thanks to a collaborative arrangement with IOS, the data of numerous
journals has been supplemented retrospectively.
• IGI Global
Almost the entire publishing catalog of IGI Global has been integrated
in the DBLP.
Preparations and arrangements have been made to integrate the future
IFIP digital library in the DBLP and to update it on a continuous basis.

Establishment of Bodies for DBLP Guidance
A DBLP Advisory Board was established in November of 2011 under the
umbrella of the LCI to support the work of the DBLP and provide
scientific oversight of the data assets. In the process ten renowned figures
from various computer science disciplines were attracted as board
members. The Advisory Board’s tasks extend to the following in
• defining guidelines, standards and priorities governing the inclusion of
data in the DBLP,
• monitoring the quality of the content of the database,
• supporting the DBLP by providing expertise, and
• representing the DBLP in the scientific community.
Members of the DBLP Advisory Board:
• Andreas Butz (Media Informatics and Human-Machine Interaction)
• Hannah Bast (Algorithms and Data Structures)
• Hans-Peter Lenhof (Bioinformatics)
• Mila Majster-Cederbaum (Complex Systems)
• Oliver Günther (Information Systems)
• Otto Spaniol (Communication and Distributed Systems)
• Rüdiger Dillmann (Humanoids and Intelligence Systems)
• Rüdiger Reischuk (Theoretical Computer Science)

5. Offerings for Dagstuhl’s Guests
Conference Facilities
The Center has three lecture halls with a seating capacity of 25 to 60 each,
in addition to several conference rooms.
The lecture halls feature Internet access in addition to state-of-the-art
presentation equipment like projectors to which laptops, PCs and video
equipment can be connected. These facilities not only enable talks and
papers to be presented in an optimal manner but also permit online
demonstrations of active and distributed systems to be given to large
audiences. An audio system and telephone and video conference
equipment are also available.
Computers and Networking
The computer equipment pool available to guests consists of several thin
clients, Apple computers and the newly added zero clients, which enable
access to virtual machines of their own. Several printers are also available.
A Wi-Fi network or wireless LAN is set up in the old building and in the
guest rooms of the new building, enabling these areas to be networked and
provided with Internet access for guests with laptops. The Wi-Fi network
also extends to the library and some of the function rooms in the old
building, providing for a large number of laptop places featuring Internet
access. Researching the library’s online catalogue can be conveniently
done from one’s own laptop.
Dedicated Link to the German Research Network
The LCI has two independent dedicated links to the German Research
Network (DFN). The main link features a bandwidth of 100 Mbit/s, the
ancillary link being operated with a bandwidth of 20 Mbit/s. The ancillary
link serves as a back-up to sustain operation in the event that the main link
should go down.
The LCI’s IT Department again has an IT specialist trainee since August of
2010. This vocational training program lasts three years and enables the
trainee to specialize in system integration.
Research Library
The Research Library is one of the Center’s most impressive offerings.
Thanks to the startup financing by the Volkswagen Foundation and
Page 31
Schloss Dagstuhl
numerous book donations of publishing houses and seminar participants, it
numbers among Germany’s key informatics research libraries.
The library collects current research literature on informatics topics for the
respective seminars, primarily in English. As of 31 December 2011, the
library’s assets totaled 58,394 bibliographic units, all of which are
contained in the online catalog. One distinguishing feature is the Center’s
impressive holdings of journals and periodicals, almost all of which are in
electronic form. Apart from the subscribed journals, the library also
provides access to several thousand other electronic journals and journal
archives via the DFG-funded national and alliance licenses.
The literature is arranged on four levels in an attractive library tower,
which also offers a large number of recesses for quiet study and research.
Being a reference library, it is at the disposal of the Dagstuhl Seminar
participants 24/7 for their research work on site. A total of five
workstations are available to the users of the library. External scholars can
also use the library provided they register beforehand.
In order to support informatics research in Germany and throughout the
world, the Center’s entire holdings of periodicals are also made available
to other libraries, particularly by way of inter-library loans. The library's
entire holdings of journals and periodicals are additionally listed in the
periodicals database and the digital library. The library is a member of
LITexpress, the Virtual Library of Rhineland-Palatinate, Saarland and the
German-speaking community of Belgium, a media loan service for the
citizens of these three areas. The library’s archive items in particular are
designed to be made available for loan.
The library also regularly arranges comprehensive book exhibits. Every
week all the books authored by the participants of the current Dagstuhl
Seminar which are available in the library are put out on display on the
first floor (one level up from the ground floor). The authors are also
requested to sign their books. If desired, book exhibits on a particular topic
are also put together by the organizers. In addition, all book donations
received from publishers are exhibited separately and the exhibits regularly
updated. This service is highly appreciated by the Center’s guests and
publishers alike.
The following can be accessed via the library’s webpage: on-line
catalogue, journal list with access to the journals available online, in
addition to other information offerings.

2011 Annual Report
Internet Offerings
In keeping with the Center’s philosophy, its Internet offerings are not only
available to the guests at Dagstuhl but to netizens throughout the world.
Objectives and content:
• Dissemination of general information on the Center, e.g. concept,
program, particulars pertaining to submitting proposals, the
• Offering participants travel information on how to get to the Center
(site plan, train and bus schedules, taxi services, etc.).
• Presenting the Research Library along with its offerings and
resources and enabling research in the Dagstuhl Library catalogue.
• Provision of information on seminars and events (e.g. seminar
objectives, scientists from whom proposals have been accepted,
• Providing a platform for exchanging materials among the seminar
The web server administers the content using the Typo3 CMS (freeware).
Apart from static pages — almost all of which are in German and English
— dynamic pages are also offered which are generated by the Center’s
proprietary software. Thus, each seminar has a dynamically generated page
of its own featuring links to a motivation text, list of participants,
publications, etc. These pages also offer the participants a platform where
they can upload and administer material on their seminar presentation
(slides, documents).
Seminar Materials
The seminar participants have the option of storing materials pertaining to
their presentation on the Dagstuhl server via the seminar’s webpage. This
procedure enables summaries of lectures, presentations or reports to be
made available to all seminar participants. This materials webpage
supports the organizers in developing the seminar’s presentation program.
The following items can also be uploaded: associated documentation like
seminar syllabuses, discussion results, tutorial scripts, reports of openproblem sessions, etc. The documents are drafts of sorts and can be
modified, supplemented or deleted by the participants at any time.

Schloss Dagstuhl
“Dagstuhl Gallery”
Exhibitions of artists are regularly organized in the cloister of the new
building. The spacious surroundings and excellent lighting provide for
striking contrasts between day and night, thus offering the artists an
excellent venue to exhibit their work. Compliments are frequently heard
with regard to the fascinating atmosphere created by the art offerings. They
provide an intriguing juxtaposition to the otherwise “ascetic” nature of the
new building.
The following exhibitions were organized in 2011:

For artist’s profiles, portfolios, concepts of the individual exhibitions,
please refer to: http://www.dagstuhl.de/ueber-dagstuhl/kunst/.
Purchasing of art through donations
Dagstuhl’s website contains a page featuring an Internet gallery enabling
participants, individuals, and groups to make contributions to Dagstuhl for
art donations. The works of art are featured on the Internet, with donations
being made by acquiring shares at affordable prices. As soon as a picture is
fully subscribed for, the donors are asked to pay in the value of the shares
subscribed by them, this enabling the art item to be purchased. This
procedure provides an incentive for the donors as they are not only
mentioned in Dagstuhl’s Internet gallery but are also mentioned on the art
item itself. It is also beneficial to the Center as the Center is able to
purchase works of art from the artists arranging exhibitions there.

Schloss Dagstuhl
The participants typically describe the atmosphere at Schloss Dagstuhl as
being surprisingly pleasant and instrumental in promoting valuable work
and communication between the guests. Former participants frequently
mention fond memories of the pleasant evenings spent in the beautiful
rooms of the manor house and making music in the Baroque Music Room.
The leisure activities offered in the Center have been chosen so as to
promote communication among the participants. Apart from the music
room featuring various instruments and sheet music, the Center also has a
poolroom and a recreation room in the basement providing for games like
pool and table football in addition to gym equipment. The following is
available in summer: sports grounds fitted with a net, boules in the yard
and mountain bikes.
Childcare Assistance
Many of our international guests would like to bring along their small
children and older kids during their stay at the Center since they would
otherwise be unable to take part in the events due to a lack of childcare
options at home. In order to promote family friendliness the Center offers
its guests experienced childcare help during the lecture and presentation

visit. The staff at the center were extremely helpful and thoughtful, taking care of all
our possible needs. The baby-sitter (Elvira) was terrific, and our daughter still talks
fondly about her and about Dagstuhl.
11031: Bidirectional Transformations "bx" (16.01. – 21.01.2011)
Hartmut Ehrig, Technical University of Berlin, Germany
Besonders schätze ich die gute Ausstattung der Bibliothek und die Idee, Bücher von
den Autoren persönlich signieren zu lassen, auch wenn das für mich einige
Zusatzarbeit bedeutet hat. Darüber hinaus ist Dagstuhl als Begegnungsstätte für
Informatiker nach wie vor einmalig gut.
11031: Bidirectional Transformations "bx" (16.01. – 21.01.2011)
Christoph Brandt, University of Luxembourg
Ich wollte mich ganz herzlich bei Ihnen für die ausgezeichnete Atmosphäre während
des Dagstuhl Seminars zum Thema "Bidirektionale Transformation" bedanken.
Wir sind zu sehr guten Ergebnissen gekommen und konnten zukünftigeKooperationen
vereinbaren. Die schöne Umgebung hat dabei sehr geholfen und hat sich wohltuend
von dem Rahmen der üblichen internationalen Tagungshotels unterschieden.
11041: Multimodal Music Processing (23.01. – 28.02.2011)
Mainard Müller, Saarland University and MPI for Informatics – Saarbrücken, Germany
Wir hatten eine fantastische Woche in Dagstuhl, die Rahmenbedingungen waren
einfach super, und wir hatten auch eine Gruppe – sehr interaktiv, sehr international,
sehr interdisziplinär.
11181: Organic Computing - Design of Self-Organizing Systems (01.05. – 06.05.2011)
Andreas Herkersdorf, Technical University of Munich, Munich, Germany
An dieser Stelle möchte ich mich ganz herzlich auch im Namen aller Organisatoren für
Ihre Hilfe und Unterstützung im Vorfeld und Vorort bei der Durchführung des
Seminars bedanken. Sie haben wesentlich zum Gelingen des Seminars beigetragen,
und Dagstuhl ist halt immer etwas Besonderes!

11291: Mathematical and Computational Foundations of Learning Theory (17.07. –
Sergei Pereverzyev, RICAM – Linz, Austria
By the way, I just have realized that this year is a kind of jubilee for me, since my
first visit to Dagstuhl was 20 years ago when I attended the Seminar 9116
"Algorithms and complexity of continuous problems". So, time is running, but the
attractivity of Dagstuhl remains unaltered.
11501: Visualization and Processing of Tensors and Higher Order Descriptors for
Multi-Valued Data (11.12. – 16.12.2011)
Markus Strommel, Saarland University, Germany
An der Universität des Saarlandes forsche ich im Bereich der
Ingenieurwissenschaften – also durchaus mehr anwendungs-orientiert. Insofern war
ich auf das Dagstuhl-Seminar sehr gespannt, ob sich hier für mich
Anknüpfungspunkte und neue Verbindungen ergeben würden. Das Seminar hat meine
Erwartungen klar übertroffen. Zum einen konnte ich aus den Vorträgen, die für mich
überwiegend auf anderen Fachgebieten lagen, interessante neue Ideen und auch
Lösungen für meine Forschungsfragestellungen aufgreifen. Zum anderen möchte ich
besonders hervorheben, dass ich mich bereits mit Teilnehmern des Seminars vor
einer Woche wieder getroffen habe und wir konkrete die Umsetzung von Ideen, die
auf dem Seminar „geboren“ wurden, in ein Forschungsprojekt angehen. Diese
Teilnehmer (Mathematiker, Informatiker) hätte ich auf den von mir üblicherweise
ingenieurwissenschaftlichen Community sicherlich nicht angetroffen.
11501: Visualization and Processing of Tensors and Higher Order Descriptors for
Multi-Valued Data (11.12. – 16.12.2011)
Peter Basser, National Institute of Child Health and Human Development, USA
I have heard from many of my associates how pleasant and informative these
meetings are, how lovely the castle is where the meeting takes place, how
stimulating is the academic environment and the delicious food.
